Hi Brandon: I would think it is possible. I have heard that the schematics are on the Palstar site, and it would be a matter of figuring out how to tie in the inductor of the box loop in place of the inductor already in the MW550P box. Steve Ratzlaff has taken one of these apart and may be able to provide more specifics.
I have been doing similar things with the Quantum Loop base unit. Using the Crate Loop, I have wound substitute "heads" to take the place of the ferrite heads, and now have a LW, MW and SW (1.8-10 mhz) versions of crate loops which plug directly into the base unit, with the base unit sitting inside the crate itself. I've cc'd your personal email with some pictures of the LW version (which uses for crates stacked together), while the MW and SW each use one crate. The gain over the corresponding ferrite head is appreciable (15-20 db at least) - in fact you have to turn the gain down to avoid overloading the circuitry, which is perhaps something to watch on the MW550P (which has a 15 db attenuator as I recall). If you have access to a Quantum Loop, Palomar Loop or similar base unit, this might be the easier way to go, since you don't have to open up the unit and make any changes. Drop me a note off-line if you want more details on this.

At 12 dB maximum, it's not really high gain, but high gain probably wouldn't be needed in your location unless the loop antenna was quite small. > >> Or were you thinking of replacing the 550P's internal inductor with the winding of your loop antenna? > > Since the MW550P has a large 6:1 vernier tuning capacitor, I was thinking the MW550P could replace the loop tuning capacitor completely and that it could perhaps sit inside the crate loop. > > Is this feasible? > > 73, > Brandon > > _______________________________________________ > IRCA mailing list > [email protected] > http://montreal.kotalampi.com/mailman/listinfo/irca > > Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers > > For more information: http://www.ircaonline.org > > To Post a message: [email protected] > > _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
